Researchers say a cheap, generic pill called finasteride prevents almost 40 percent of low-grade prostate cancers without increasing the risk of dying from more aggressive tumors.
New evidence points to the drug as a potentially safer way to deal with prostate cancers that now get more intense treatment. Many prostate cancers that aren't destined to cause men serious health problems are often treated with surgery or radiation.
When Sally O'Neill's doctor told her she had an early form of cancer in one of her breasts, she didn't agonize about what she wanted to.
The 42-year-old mother of two young girls wanted a double mastectomy.
"I decided at that moment that I wanted them both taken off," says O'Neill, who lives in a suburb of Boston. "There wasn't a real lot of thought process to it. I always thought, 'If this happens to me, this is what I'm going to do.' Because I'm not taking any chances. I want the best possible outcome. I don't want to do a wait-and-see."
